LEON GAUMON'I, PARIS. FRANCE. ASSIGNOR TO SOCIETE DES- ETABLISSEMENTSGAUMO'NT, OF PARIS, FRANCE.

To all whom z't may concern Be it known that I; Lriox GAUMOXT, a citizenof the French Republic, and a resident of Paris, France, have inventedcertain Improvements in Synchronizing Devices, of which the following isa specification.

This invention relates to certain improvements in synchronizing devices,and being a division of my application Serial No. 404,712, filed Dec. 2,1907, which in turn is a divison of my application filed Jan. 4, 1907,Serial No. 350,857, and the object of the invention is to provide adevice of this general cha racter of a simple and comparativelyinexpensive natu-re, which shall permit of maintaining a substantiallysynchronous or timed relation between a phonograph and a kinematograph,so'that the same may be synchronously operated in a substantiallyautomatic manner permitting music, singing, speaking, or other sounds tobe reproduced from the phonograph in accurate relation to a 'movingpicture exhibition given from the 'kinematograph, without requiring anyparticular care or attention upon the part of the attendant.

The invention consists in certain novel features of the construction,and combinations and arrangements of the several parts of the improvedsynchronizing device, whereby certaiu important advantages are attained,and the device is rendered simpler, less expensive, and otherwise betteradapted and more convenient for use, all as will be hereinafter fullyset forth.

The novel features of the inventionwill be carefully defined in theclaims.

In order that my improvements may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 a somewhat diagraphic view illustrating oneembodiment of the improved synchronizing device, and Fig. is a d1agramillustrating certain of the c1rcuitconnections which are not clearlyshown. in

In these drawings I have illustrated (ha-- graphically an arrangement ofthe synchronizing device comprised in my present mvention andparticularly adapted for maintaining a synchronous relation betweenakinematograph A and a phonograph l3,

' Original application filed December 2, 1907, Serial No. 404,712.Divided and this application filed February Serial No; 478,453.

and wherein the kinematograph motor is adapted to be controlled directlyfrom the movement of the phonograph motor, or from the phonographactuated therefrom. In this formation of the device, the kinen'aatographmotor 25 is arranged to operate at four times the speed of thephonograph motor, and-is provided with six poles 54, the coils of whichare connected by means conductors 53, with binding posts 52', carriedupon a circular part 52 adjacent either to a rotati-ve part of thephonograph, or-to some member turningdn unison therewith. The part 52carries an annular series of contact plates 50, arranged in four groups,each group comprising sixsuch plates lettered a, b, c, d, e and f,uponthe drawing, the corresponding plates a, a, b, 6, etc, of theseveral groups being electrically connected with each other by means ofconductors 51 and being alsoconnected with the binding posts 52 by meansof conductors 51, as shown in dotted lines upon the drawin whereby itwill be seen that the corresponding plates (1, a, 7), b,' etc., of theseveral groups are in electrical communicationwith the severalfieldto-ils of the kinematograph motor 25.

49 and 49 represent brushes carried by contact rings 47 and N which arearranged to turn with the phonograph or other part moving in unisontherewith, said brushes being thus adapted to traverse the successivecontact plates 50, 50, of the annular series. 46 and 46* are otherbrushes, hereby the contact -rings 47 and 47 are maintained inelectrical communication with conductors 45 and 45 which are included inthe field circuit 26 of the kinematograph motor 25.

40 represents a controlling switch having its lever adapted, when movedin one posi' tion, for communication with a contact 41, from whichextended a conductor 42, which includes the windings of an electromagnet4-3, and is so connected in the field circuit 26 of motor 25 as to shortcircuit the conductors 45 and 45 together with the field coils of saidmotor and the intercommunieating parts when the'switch is adjusted toinclude said conductor 42 in said field circuit.

44 represents a detent lever having a spring, the tension of which isnormally exerted to move said lc\ci' in the path ol a projection ll"carried by a moving part of the phonograph in such a way as normally toprevent the operation of the phonograph. The lever 44 is arranged as thearmature lever of the electro-niagnet 43. whereby it will be seen thatwhen the switch-40 is moved to connect the windings of said magnet inthe motor field circuit 2 and thereby to energize said magnet, the leverit is moved against the tension ot'its spring and is thereby disengagedfrom the projection '44 upon the moving part of the phonograph.

It being presumed that the phonograph is driven by a band C or the likefrictional driving connection from a motor D,"which may thus be operatedirrespective of the engagement of the detent lever 44 with theprojection 44 of the moving part of the phonograph, since the band orother trictional driving connection will slip at such times as saiddetcnt le'icr thrown by its spring into position to hold the. phonographout of operation, it will be seen that when the switch lever is throwninto communication with the contact 41 to energize the magnet 43, thedetent lever 44 being thereby disengaged fronithe projection 14 thephonograph motor will bej permitted to operate the phonograph\QliQII'QbYg the projection 44 will be'immediatelv removed out ofposition for engagement withfthesa-idodetcnt lever it when the same isagain -t-l'irown by the tension of its spring uponlhe dei nergization ofthe electro-magnet 43. After the 'phonograph isthus set in operation,the si'vitch lever 40 is further moved by the attendant to the positionshown in the drawing.whereby communication with contact 41 isinterrupted and magnet -13 is decnergized', and communication withconductor 45* is established through contact 48, the circuits of thekinematograph motor being thereby com pleted. so that operatit'in of thekinematograph driven from said motor thereupon commences. The armaturecircuit of said hineuiatograph motor is represented at 26. and the fieldcircuit 26 thereof comprises conductor 45, ring 47. brush 4!). contactdevices 50 and 51, and conductor 52} leading to the field windings 5tand thence returning by another conductor 53 and contact devices 51 and50 to brush 49", ring 47 and conductor 45, and it will be seen thatsince the brushes 49 and 49. which control the several field windingsot' the lrinematograph with the phonograph. a direct control is therebyexerted to insure svncliron'ous opcr ation of the kinematograph motor.
